FIELD OF THE INVENTION

This invention relates to a catalyst and use of the catalyst for processing of hydrocarbon feedstreams that contain aromatics.

BACKGROUND OF THE INVENTION

Porous inorganic solids have found great utility as catalysts and separation media for industrial application. In particular, mesoporous materials, such as silicas and aluminas, having a periodic arrangement of mesopores are attractive materials for use in catalysis processes due to their uniform and tunable pores, high surface areas and large pore volumes. Such mesoporous materials are known to have large specific surface areas (e.g., 1000 m²/g) and large pore volumes (e.g., 1 cm³/g). For these reasons, such mesoporous materials enable reactive catalysts.

For example, hydrofinishing technologies have used both base and noble metal catalysts on a mesoporous support. With noble metal catalysts, excellent color and oxidation stability can be achieved at lower pressures and temperatures with smaller reactor volumes than those required when using base metal catalysts. At higher processing temperatures, color quality is sacrificed to achieve sufficient oxidation stability. With noble metal catalysts, it is possible to get superior color stability (water-white), excellent oxidation stability, and almost complete removal of aromatics.

However, mesoporous organosilicas, which may be used as a catalyst support, are conventionally formed by the self-assembly of the silsequioxane precursor in the presence of a structure directing agent, a porogen and/or a framework element. The precursor is hydrolysable and condenses around the structure directing agent. These materials have been referred to as Periodic Mesoporous Organosilicates (PMOs), due to the presence of periodic arrays of parallel aligned mesoscale channels. For example, Landskron, K., et al. [Science, 302:266-269 (2003)] report the self-assembly of 1,3,5-tris[diethoxysila]cylcohexane[(EtO)₂SiCH₂]₃ in the presence of a base and the structure directing agent, cetyltrimethylammonium bromide, to form PMOs that are bridged organosilicas with a periodic mesoporous framework, which consist of SiO₃R or SiO₂R₂ building blocks, where R is a bridging organic group. In PMOs, the organic groups can be homogenously distributed in the pore walls. U.S. Pat. Pub. No. 2012/0059181 reports the preparation of a crystalline hybrid organic-inorganic silicate formed from 1,1,3,3,5,5 hexaethoxy-1,3,5trisilyl cyclohexane in the presence of NaAlO₂ and base. U.S. Patent Application Publication No. 2007/003492 reports preparation of a composition formed from 1,1,3,3,5,5 hexaethoxy-1,3,5trisilyl cyclohexane in the presence of propylene glycol monomethyl ether.

However, the use of a structure directing agent, such as a surfactant, in the preparation of an organosilica material, requires a complicated, energy intensive process to eliminate the structure directing agent at the end of the preparation process. For example, calcining may be required as well as wastewater disposal steps and associated costs to dispose of the structure directing agent. This limits the ability to scale-up the process for industrial applications.

Therefore, there is a need for improved catalysts and/or processes for aromatic saturation of hydrocarbon feeds using organosilica materials that can be prepared by a method that can be practiced in the absence of a structure directing agent, a porogen or surfactant.

SUMMARY OF THE INVENTION

It has been found that catalyst supports comprising organosilica material with desirable pore diameter, pore volume, and surface area can be achieved. Further, such organosilica material supports can be successfully prepared without the need for a structure directing agent, a porogen or surfactant.

In still another aspect, embodiments of the invention provide a method of making a hydrogenation catalyst for aromatic hydrogenation, the method comprising: a) providing an aqueous mixture that contains essentially no structure directing agent and/or porogen, (b) adding at least one compound of Formula [Z¹⁵Z¹⁶SiCH₂]₃ (VII) into the aqueous mixture to form a solution, wherein each Z¹⁵ represents a C₁-C₄ alkoxy group and each Z¹⁶ represents a C₁-C₄ alkoxy group or a C₁-C₄ alkyl group; (c) aging the solution to produce a gel; (d) drying the gel to obtain an organosilica material support which is a polymer comprising independent units of a monomer of Formula [Z¹OZ²OSiCH₂]₃ (I), wherein each Z¹ and Z² independently represent a hydrogen atom, a C₁-C₄ alkyl group or a bond to a silicon atom of another monomer; and (e) impregnating the organosilica material support with at least one catalyst metal selected from the group consisting of a Group 8 metal, a Group 9 metal, a Group 10 metal and a combination thereof.

In still another aspect, embodiments of the invention provide an aromatics hydrogenation process for a hydrocarbon feedstream comprising: a) contacting a hydrocarbon feedstream comprising aromatics with a hydrogenation catalyst in the presence of a hydrogen-containing treat gas in a first reaction stage operated under effective aromatics hydrogenation conditions to produce a reaction product with reduced aromatics content, wherein the hydrogenation catalyst comprises: (i) an organosilica material support, which is a polymer comprising independent units of a monomer of Formula [Z¹OZ²OSiCH₂]₃ (I), wherein each Z¹ and Z² independently represent a hydrogen atom, a C₁-C₄ alkyl group or a bond to a silicon atom of another monomer; and (ii) at least one catalyst metal selected from the group consisting of a Group 8 metal, a Group 9 metal, a Group 10 metal and a combination thereof.

Using surfactant as a template to synthesize mesoporous materials can create highly ordered structure, e.g. well-defined cylindrical-like pore channels. In some circumstances, there may be no hysteresis loop observed from N₂ adsorption isotherm. In other circumstances, for instance where mesoporous materials can have less ordered pore structures, a hysteresis loop may be observed from N₂ adsorption isotherm experiments. In such circumstances, without being bound by theory, the hysteresis can result from the lack of regularity in the pore shapes/sizes and/or from bottleneck constrictions in such irregular pores.

Additionally or alternatively, the catalyst metal may be present in an amount of at least about 0.010 wt. %, at least about 0.050 wt. %, at least about 0.10 wt. %, at least about 0.20 wt. %, at least about 0.40 wt. %, at least about 0.50 wt. %, at least about 0.60 wt. %, at least about 0.80 wt. %, at least about 1.0 wt. %, at least about 1.2 wt. %, at least about 1.4 wt. %, at least about 1.5 wt. %, at least about 1.6 wt. %, at least about 1.8 wt. %, at least about 2.0 wt. %, at least about 2.2 wt. %, at least about 2.4 wt. %, at least about 2.6 wt. %, at least about 2.8 wt. %, at least about 3.0 wt. %, at least about 3.5 wt. %, or at least about 4.0 wt. %. All metals weight percents are on support. By “on support” it is meant that the percents are based on the weight of the support, i.e., the organosilica material support and optionally, binder material. For example, if the support were to weigh 100 grams, then 20 wt. % catalyst metal would mean that 20 grams of the catalyst metal was on the support.

In particular, the catalyst metal may be present in an amount of about 0.010 wt. % to about 4.0 wt. %, about 0.05 wt. % to about 3.5 wt. %, about 0.1 wt. % to about 2.0 wt. %, or about 0.1 wt. % to about 1.4 wt. %.

The catalyst metal can be incorporated into the organosilica material support by any convenient method, such as by impregnation, by ion exchange, by complexation to surface sites or physically admixed with the organosilica material support. If the catalyst metal is to be impregnated into or exchanged onto the organosilica material support and optionally, binder, it may be done, for example, by treating the organosilica material support with a suitable ion containing the catalyst metal. If the catalyst metal is platinum, suitable platinum compounds include chloroplatinic acid, platinous chloride and various compounds containing the platinum amine complex. The catalyst metal may also be incorporated into, onto, or with the composited support and binder material by utilizing a compound(s) wherein the catalyst metal is present in the cation of the compound and/or compounds or in which it is present in the anion of the compound(s). It should be noted that both cationic and anionic compounds can be used. Non-limiting examples of suitable palladium or platinum compounds in which the metal is in the form of a cation or cationic complex are Pd(NH₃)₄Cl₂ or Pt(NH₃)₄Cl₂ are particularly useful, as are anionic complexes such as the vanadate and metatungstate ions. Cationic forms of other metals are also very useful since they may be exchanged onto the crystalline material or impregnated into it.

The catalyst metal so incorporated may be employed to promote any one of a number of catalytic tranformations commonly conducted in petroleum refining or petrochemicals production. Examples of such catalytic processes can include, but are not limited to, hydrogenation, dehydrogenation, aromatization, aromatic saturation, hydrodesulfurization, olefin oligomerization, polymerization, hydrodenitrogenation, hydrocracking, naphtha reforming, paraffin isomerization, aromatic transalkylation, saturation of double/triple bonds, and the like, as well as combinations thereof. In particular, the catalyst metal may be employed for aromatic hydrogenation and/or saturation.

II.C. Binder

In various aspects, the hydrogenation catalyst may further comprise a binder or be self-bound. Suitable binders, include but are not limited to active and inactive materials, synthetic or naturally occurring zeolites, as well as inorganic materials such as clays and/or oxides such as silica, alumina, zirconia, titania, silica-alumina, cerium oxide, magnesium oxide, or combinations thereof. In particular, the binder may be selected from the group consisting of active and inactive materials, inorganic materials, clays, alumina, silica, silica-alumina, titania, zirconia, or a combination thereof. Particularly, the binder may be silica-alumina, alumina and/or zirconia, particularly alumina. Silica-alumina may be either naturally occurring or in the form of gelatinous precipitates or gels including mixtures of silica and metal oxides. It should be noted it is recognized herein that the use of a material in conjunction with a zeolite binder material, i.e., combined therewith or present during its synthesis, which itself is catalytically active may change the conversion and/or selectivity of the finished catalyst. It is also recognized herein that inactive materials can suitably serve as diluents to control the amount of conversion if the present invention is employed in alkylation processes so that alkylation products can be obtained economically and orderly without employing other means for controlling the rate of reaction. These inactive materials may be incorporated into naturally occurring clays, e.g., bentonite and kaolin, to improve the crush strength of the catalyst under commercial operating conditions and function as binders or matrices for the catalyst. The catalysts described herein typically can comprise, in a composited form, a ratio of support material to binder material of about 100 parts support material to about zero parts binder material; about 99 parts support material to about 1 parts binder material; about 95 parts support material to about 5 parts binder material. Additionally or alternatively, the catalysts described herein typically can comprise, in a composited form, a ratio of support material to binder material ranging from about 90 parts support material to about 10 parts binder material to about 10 parts support material to about 90 parts binder material; about 85 parts support material to about 15 parts binder material to about 15 parts support material to about 85 parts binder material; about 80 parts support material to 20 parts binder material to 20 parts support material to 80 parts binder material, all ratios being by weight, typically from 80:20 to 50:50 support material:binder material, preferably from 65:35 to 35:65. Compositing may be done by conventional means including mulling the materials together followed by extrusion of pelletizing into the desired finished catalyst particles.

II.D. Further Metals

In some embodiments, the organosilica material support can further comprise cationic metal sites incorporated into the network structure. Such cationic metal sites may be incorporated by any convenient method, such as impregnation or complexation to the surface, through an organic precursor, or by some other method. This organometallic material may be employed in a number of hydrocarbon separations conducted in petroleum refining or petrochemicals production. Examples of such compounds to be desirably separated from petrochemicals/fuels can include olefins, paraffins, aromatics, and the like.

Additionally or alternatively, the organosilica material support can further comprise a surface metal incorporated within the pores of the organosilica material. The surface metal can be selected from a Group 1 element, a Group 2 element, a Group 13 element, and a combination thereof. When a Group 1 element is present, it can preferably comprise or be sodium and/or potassium. When a Group 2 element is present, it can include, but may not be limited to, magnesium and/or calcium. When a Group 13 element is present, it can include, but may not be limited to, boron and/or aluminum.

One or more of the Group 1, 2, 6, 8-10 and/or 13 elements may be present on an exterior and/or interior surface of the organosilica material support. For example, one or more of the Group 1, 2 and/or 13 elements may be present in a first layer on the organosilica material and one or more of the Group 6, 8, 9 and/or 10 elements may be present in a second layer, e.g., at least partially atop the Group 1, 2 and/or 13 elements. Additionally or alternatively, only one or more Group 6, 8, 9 and/or 10 elements may present on an exterior and/or interior surface of the organosilica material. The surface metal(s) can be incorporated into/onto the organosilica material by any convenient method, such as by impregnation, deposition, grafting, co-condensation, by ion exchange, and/or the like. In particular, a Group 13 metal, such as, but not limited to, aluminum may be grafted onto a surface of the organosilica material support. Additionally or alternatively, a Group 4 metal, such as, but not limited to, titanium, zirconium and hafnium, may be grafted onto a surface of the organosilica material support.

III. Methods of Making Hydrogenation Catalysts

In another embodiment, methods of producing the hydrogenation catalysts described herein for aromatic saturation are provided. The method comprises:

(a) providing an aqueous mixture that contains essentially no structure directing agent and/or porogen;

(b) adding at least one compound of Formula [Z¹⁵Z¹⁶SiCH₂]₃ (VII) into the aqueous mixture to form a solution, wherein each Z¹⁵ can be a C₁-C₄ alkoxy group and each Z¹⁶ can be a C₁-C₄ alkoxy group or a C₁-C₄ alkyl group;

(c) aging the solution to produce a pre-product; and

(d) drying the pre-product to obtain an organosilica material support which is a polymer comprising independent units of a monomer of Formula [Z¹OZ²OSiCH₂]₃ (I), as described herein; and

(e) impregnating the organosilica material support with at least one catalyst metal selected from the group consisting of a Group 8 metal, a Group 9 metal, a Group 10 metal and a combination thereof.

Additionally or alternatively, the at least one compound of Formula [Z¹⁵Z¹⁶SiCH₂]₃ (VII) can be added in step (b) as at least partially hydroxylated and/or as at least partially polymerized/oligomerized, such that each Z¹⁵ and/or Z¹⁶ can more broadly represent a hydroxyl group, a C₁-C₄ alkoxy group, a C₁-C₄ alkyl group, or an oxygen atom bonded to a silicon atom of another siloxane. In other words, an unaged pre-product can be added in step (b), in addition to or as an alternative to the monomeric (at least one) compound of Formula [Z¹⁵Z¹⁶SiCH₂]₃ (VII) and yet still form the polymer in step (d).

III.A. Aqueous Mixture

The organosilica materials described herein may be made using essentially no structure directing agent or porogen. Thus, the aqueous mixture contains essentially no added structure directing agent and/or no added porogen.

As used herein, “no added structure directing agent,” and “no added porogen” means either (i) there is no component present in the synthesis of the organosilica material that aids in and/or guides the polymerization and/or polycondensing and/or organization of the building blocks that form the framework of the organosilica material; or (ii) such component is present in the synthesis of the organosilica material in a minor, or a non-substantial, or a negligible amount such that the component cannot be said to aid in and/or guide the polymerization and/or polycondensing and/or organization of the building blocks that form the framework of the organosilica material. Further, “no added structure directing agent” is synonymous with “no added template” and “no added templating agent.”

1. Structure Directing Agent

Examples of a structure directing agent can include, but are not limited to, non-ionic surfactants, ionic surfactants, cationic surfactants, silicon surfactants, amphoteric surfactants, polyalkylene oxide surfactants, fluorosurfactants, colloidal crystals, polymers, hyper branched molecules, star-shaped molecules, macromolecules, dendrimers, and combinations thereof. Additionally or alternatively, the surface directing agent can comprise or be a poloxamer, a triblock polymer, a tetraalkylammonium salt, a nonionic polyoxyethylene alkyl, a Gemini surfactant, or a mixture thereof. Examples of a tetraalkylammonium salt can include, but are not limited to, cetyltrimethylammonium halides, such as cetyltrimethylammonium chloride (CTAC), cetyltrimethylammonium bromide (CTAB), and octadecyltrimethylammonium chloride. Other exemplary surface directing agents can additionally or alternatively include hexadecyltrimethylammonium chloride and/or cetylpyridinium bromide.

Poloxamers are block copolymers of ethylene oxide and propylene oxide, more particularly nonionic triblock copolymers composed of a central hydrophobic chain of polyoxypropylene (poly(propylene oxide)) flanked by two hydrophilic chains of polyoxyethylene (poly(ethylene oxide)). Specifically, the term “poloxamer” refers to a polymer having the formula HO(C₂H₄))a(C₃H₆O)_(b)(C₂H₄O)_(a)H in which “a” and “b” denote the number of polyoxyethylene and polyoxypropylene units, respectively. Poloxamers are also known by the trade name Pluronic®, for example Pluronic® 123 and Pluronic® F127. An additional triblock polymer is B50-6600.

Nonionic polyoxyethylene alkyl ethers are known by the trade name Brij®, for example Brij® 56, Brij® 58, Brij® 76, Brij ® 78. Gemini surfactants are compounds having at least two hydrophobic groups and at least one or optionally two hydrophilic groups per molecule have been introduced.

2. Porogen

A porogen material is capable of forming domains, discrete regions, voids and/or pores in the organosilica material. An example of a porogen is a block copolymer (e.g., a di-block polymer). As used herein, porogen does not include water. Examples of polymer porogens can include, but are not limited to, polyvinyl aromatics, such as polystyrenes, polyvinylpyridines, hydrogenated polyvinyl aromatics, polyacrylonitriles, polyalkylene oxides, such as polyethylene oxides and polypropylene oxides, polyethylenes, polylactic acids, polysiloxanes, polycaprolactones, polycaprolactams, polyurethanes, polymethacrylates, such as polymethylmethacrylate or polymethacrylic acid, polyacrylates, such as polymethylacrylate and polyacrylic acid, polydienes such as polybutadienes and polyisoprenes, polyvinyl chlorides, polyacetals, and amine-capped alkylene oxides, as well as combinations thereof.

Additionally or alternatively, porogens can be thermoplastic homopolymers and random (as opposed to block) copolymers. As used herein, “homopolymer” means compounds comprising repeating units from a single monomer. Suitable thermoplastic materials can include, but are not limited to, homopolymers or copolymers of polystyrenes, polyacrylates, polymethacrylates, polybutadienes, polyisoprenes, polyphenylene oxides, polypropylene oxides, polyethylene oxides, poly(dimethylsiloxanes), polytetrahydrofurans, polyethylenes, polycyclohexylethylenes, polyethyloxazolines, polyvinylpyridines, polycaprolactones, polylactic acids, copolymers of these materials and mixtures of these materials. Examples of polystyrene include, but are not limited to anionic polymerized polystyrene, syndiotactic polystyrene, unsubstituted and substituted polystyrenes (for example, poly(α-methyl styrene)). The thermoplastic materials may be linear, branched, hyperbranched, dendritic, or star like in nature.

Additionally or alternatively, the porogen can be a solvent. Examples of solvents can include, but are not limited to, ketones (e.g., cyclohexanone, cyclopentanone, 2-heptanone, cycloheptanone, cyclooctanone, cyclohexylpyrrolidinone, methyl isobutyl ketone, methyl ethyl ketone, acetone), carbonate compounds (e.g., ethylene carbonate, propylene carbonate), heterocyclic compounds (e.g., 3-methyl-2-oxazolidinone, dimethylimidazolidinone, N-methylpyrrolidone, pyridine), cyclic ethers (e.g., dioxane, tetrahydrofuran), chain ethers (e.g., diethyl ether, ethylene glycol dimethyl ether, propylene glycol dimethyl ether, tetraethylene glycol dimethyl ether, polyethylene glycol dimethyl ether, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, propylene glycol monomethyl ether (PGME), triethylene glycol monobutyl ether, propylene glycol monopropyl ether, triethylene glycol monomethyl ether, diethylene glycol ethyl ether, diethylene glycol methyl ether, dipropylene glycol methyl ether, dipropylene glycol dimethyl ether, propylene glycol phenyl ether, tripropylene glycol methyl ether), alcohols (e.g., methanol, ethanol), polyhydric alcohols (e.g., ethylene glycol, propylene glycol, polyethylene glycol, polypropylene glycol, glycerin, dipropylene glycol), nitrile compounds (e.g., acetonitrile, glutarodinitrile, methoxyacetonitrile, propionitrile, benzonitrile), esters (e.g., ethyl acetate, butyl acetate, methyl lactate, ethyl lactate, methyl methoxypropionate, ethyl ethoxypropionate, methyl pyruvate, ethyl pyruvate, propyl pyruvate, 2-methoxyethyl acetate, ethylene glycol monoethyl ether acetate, propylene glycol monomethyl ether acetate (PGMEA), butyrolactone, phosphoric acid ester, phosphonic acid ester), aprotic polar substances (e.g., dimethyl sulfoxide, sulfolane, dimethylformamide, dimethylacetamide), nonpolar solvents (e.g., toluene, xylene, mesitylene), chlorine-based solvents (e.g., methylene dichloride, ethylene dichloride), benzene, dichlorobenzene, naphthalene, diphenyl ether, diisopropylbenzene, triethylamine, methyl benzoate, ethyl benzoate, butyl benzoate, monomethyl ether acetate hydroxy ethers such as dibenzylethers, diglyme, triglyme, and mixtures thereof.

V. Aromatic Hydrogenation Process

In various embodiments, an aromatics hydrogenation process for a hydrocarbon feedstream is provided herein. The aromatics hydrogenation process can comprise contacting a hydrocarbon feedstream comprising aromatics with a hydrogenation catalyst as described herein in the presence of a hydrogen-containing treat gas in a first reaction stage operated under effective aromatics hydrogenation conditions to produce a reaction product with reduced aromatics content. As understood herein, a hydrogenation catalyst can be used for both hydrogenation and aromatic saturation of a feedstream. Similarly, a hydrogenation process can refer to either hydrogenation or aromatic saturation of a feedstream.

In various embodiments, the hydrogenation process can be achieved by contacting a hydrocarbon feedstream with a hydrogenation catalyst described herein in the presence of a hydrogen-containing treat gas in a first reaction stage operated under effective aromatics hydrogenation conditions to produce a reaction product with reduced aromatics content.

Hydrogen-containing treat gasses suitable for use in a hydrogenation process can be comprised of substantially pure hydrogen or can be mixtures of other components typically found in refinery hydrogen streams. It is preferred that the hydrogen-containing treat gas stream contains little, more preferably no, hydrogen sulfide. The hydrogen-containing treat gas purity should be at least about 50% by volume hydrogen, preferably at least about 75% by volume hydrogen, and more preferably at least about 90% by volume hydrogen for best results. It is most preferred that the hydrogen-containing stream be substantially pure hydrogen.

Feedstreams suitable for hydrogenation by the hydrogenation catalyst described herein include any conventional hydrocarbon feedstreams where hydrogenation or aromatic saturation is desirable. Typically, an input feed for an aromatic saturation process can be generated as a product or side-product from a previous type of hydroprocessing, such as hydrocracking for fuels or lubricant base stock production. A wide range of petroleum and chemical feedstocks can be hydroprocessed. Such feedstreams can include hydrocarbon fluids, diesel, kerosene, lubricating oil feedstreams, heavy coker gasoil (HKGO), de-asphalted oil (DAO), FCC main column bottom (MCB), steam cracker tar. Such feedstreams can also include other distillate feedstreams such as light to heavy distillates including raw virgin distillates, wax-containing feedstreams such as feeds derived from crude oils, shale oils and tar sands. Synthetic feeds such as those derived from the Fischer-Tropsch process can also be aromatically saturated using the hydrogenation catalyst described herein. Typical wax-containing feedstocks for the preparation of lubricating base oils have initial boiling points of about 315° C. or higher, and include feeds such as whole and reduced petroleum crudes, hydrocrackates, raffinates, hydrotreated oils, gas oils (such as atmospheric gas oils, vacuum gas oils, and coker gas oils), atmospheric and vacuum residues, deasphalted oils/residua (e.g., propane deasphalted residua, brightstock, cycle oil), dewaxed oils, slack waxes and Fischer-Tropsch wax, and mixtures of these materials. Such feeds may be derived from distillation towers (atmospheric and vacuum), hydrocrackers, hydrotreaters and solvent extraction units, and may have wax contents of up to 50% or more. Preferred lubricating oil boiling range feedstreams include feedstreams which boil in the range of 650-1100° F. Diesel boiling range feedstreams include feedstreams which boil in the range of 480-660° F. Kerosene boiling range feedstreams include feedstreams which boil in the range of 350-617° F.

Hydrocarbon feedstreams suitable for use herein also contain aromatics and nitrogen- and sulfur-contaminants. Feedstreams containing up to 0.2 wt. % of nitrogen, based on the feedstream, up to 3.0 wt. % of sulfur, and up to 50 wt. % aromatics can be used in the present process In various embodiments, the sulfur content of the feedstreams can be below about 500 wppm, or below about 300 wppm, or below about 200 wppm, or below about 100 wppm, or below about 50 wppm, or below about 15wppm. The pressure used during an aromatic hydrogenation process can be modified based on the expected sulfur content in a feedstream. Feeds having a high wax content typically have high viscosity indexes of up to 200 or more. Sulfur and nitrogen contents may be measured by standard ASTM methods D2622 (sulfur), and D5453 and/or D4629 (nitrogen), respectively.

Effective hydrogenation conditions may be considered to be those conditions under which at least a portion of the aromatics present in the hydrocarbon feedstream are saturated, preferably at least about 50 wt. % of the aromatics are saturated, more preferably greater than about 75 wt. %. Effective hydrogenation conditions can include temperatures of from 150° C. to 400° C., a hydrogen partial pressure of from 740 to 20786 kPa (100 to 3000 psig), a space velocity of from 0.1 to 10 liquid hourly space velocity (LHSV), and a hydrogen to feed ratio of from 89 to 1780 m³/m³ (500 to 10000 scf/B).

Additionally or alternatively, effective hydrogenation conditions may be conditions effective at removing at least a portion of the nitrogen and organically bound sulfur contaminants and hydrogenating at least a portion of said aromatics, thus producing at least a liquid lube boiling range product having a lower concentration of aromatics and nitrogen and organically bound sulfur contaminants than the lube boiling range feedstream.

Additionally or alternatively, effective hydrogenation conditions may be conditions effective at removing at least a portion of the nitrogen and organically bound sulfur contaminants and hydrogenating at least a portion of said aromatics, thus producing at least a liquid diesel boiling range product having a lower concentration of aromatics and nitrogen and organically bound sulfur contaminants than the diesel boiling range feedstream.

As stated above, in some instances, the hydrocarbon feedstream (e.g., lube oil boiling range) may be hydrotreated to reduce the sulfur contaminants to below about 500 wppm, particularly below about 300 wppm, particularly below about 200 wppm or particularly below about 100 wppm. In such an embodiment, the process may comprise at least two reaction stages, the first reaction state containing a hydrotreating catalyst operated under effective hydrotreating conditions, and the second containing a hydrogenation catalyst has described herein operated under effective hydrogenation conditions as described above. Therefore, in such an embodiment, the hydrocarbon feedstream can be first contacted with a hydrotreating catalyst in the presence of a hydrogen-containing treat gas in a first reaction stage operated under effective hydrotreating conditions in order to reduce the sulfur content of the feedstream to within the above-described range. Thus, the term “hydrotreating” as used herein refers to processes wherein a hydrogen-containing treat gas is used in the presence of a suitable catalyst that is active for the removal of heteroatoms, such as sulfur, and nitrogen. Suitable hydrotreating catalysts for use in the present invention are any conventional hydrotreating catalyst and includes those which are comprised of at least one Group 8 metal, preferably Fe, Co and Ni, more preferably Co and/or Ni, and most preferably Ni; and at least one Group 6 metal, preferably Mo and W, more preferably Mo, on a high surface area support material, preferably alumina. Additionally or alternatively, more than one type of hydrotreating catalyst can be used in the same reaction vessel. The Group 8 metal may typically be present in an amount ranging from about 2 to 20 wt. %, preferably from about 4 to 12 wt. %. The Group 6 metal can typically be present in an amount ranging from about 5 to 50 wt. %, preferably from about 10 to 40 wt. %, and more preferably from about 20 to 30 wt. %. All metals weight percents are “on support” as described above.

Effective hydrotreating conditions may be considered to be those conditions that can effectively reduce the sulfur content of the feedstream (e.g., lube oil boiling range) to within the above-described ranges. Typical effective hydrotreating conditions can include temperatures ranging from about 150° C. to about 425° C., preferably about 200° C. to about 370° C., more preferably about 230° C. to about 350° C. Typical weight hourly space velocities (“WHSV”) may range from about 0.1 to about 20 hr⁻¹, preferably from about 0.5 to about 5 hr⁻¹. Any effective pressure can be utilized, and pressures can typically range from about 4 to about 70 atmospheres (405 to 7093 kPa), preferably 10 to 40 atmospheres (1013 to 4053 kPa). In a particular embodiment, said effective hydrotreating conditions may be conditions effective at removing at least a portion of said organically bound sulfur contaminants and hydrogenating at least a portion of said aromatics, thus producing at least a reaction product (e.g., liquid lube oil boiling range product) having a lower concentration of aromatics and organically bound sulfur contaminants than the lube oil boiling range feedstream.

The contacting of the hydrocarbon feedstream with the hydrotreating catalyst may produce a reaction product comprising at least a vapor product and a liquid product. The vapor product may typically comprise gaseous reaction products, such as H₂S, and the liquid reaction product may typically comprise a liquid hydrocarbon having a reduced level of nitrogen and sulfur contaminants. The total reaction product can be passed directly into the second reaction stage, but it may be preferred that the gaseous and liquid reaction products be separated, and the liquid reaction product conducted to the second reaction stage. Thus, in one embodiment, the vapor product and the liquid product may be separated, and the liquid product may be conducted to the second reaction stage. The method of separating the vapor product from the liquid product can be accomplished by any means known to be effective at separating gaseous and liquid reaction products. For example, a stripping tower or reaction zone can be used to separate the vapor product from the liquid product (e.g., liquid lube oil boiling range product). The liquid product thus conducted to the second reaction stage can have a sulfur concentration within the range of about 500 wppm, particularly below about 300 wppm, or particularly below about 200 wppm or particularly below about 100 wppm.

In still other embodiments, the hydrogenation catalysts described herein can be used in integrated hydroprocessing methods. In addition to the hydrofinishing and/or aromatic hydrogenation/saturation processes involving the hydrogenation catalyst described herein, an integrated hydroprocessing method can also include various combinations of hydrotreating, hydrocracking, catalytic dewaxing (such as hydrodewaxing), and/or solvent dewaxing. The scheme of hydrotreating followed by hydrofinishing described above represents one type of integrated process flow. Another integrated processing example is to have a dewaxing step, either catalytic dewaxing or solvent dewaxing, followed by hydroprocessing with the hydrogenation catalysts described herein. Still another example is a process scheme involving hydrotreating, dewaxing (catalytic or solvent), and then hydroprocessing with the hydrogenation catalysts described herein. Yet another example is hydroprocessing with the hydrogenation catalysts described herein followed by dewaxing (catalytic or solvent). Alternatively, multiple hydrofinishing and/or aromatic hydrogenation steps can be employed with hydrotreatment, hydrocracking, or dewaxing steps. An example of such a process flow is hydrofinishing, dewaxing (catalytic or solvent), and then hydrofinishing again, where at least one of the hydrofinishing steps may use a hydrogenation catalysts described herein. For processes involving catalytic dewaxing, effective catalytic dewaxing conditions can include temperatures of from 150° C. to 400° C., preferably 250° C. to 350° C., pressures of from 791 to 20786 kPa (100 to 3000 psig), preferably 1480 to 17338 kPa (200 to 2500 psig), liquid hourly space velocities of from 0.1 to 10 hr −¹, preferably 0.1 to 5 hr ⁻¹ and hydrogen treat gas rates from 45 to 1780 m³/m³ (250 to 10000 scf/B), preferably 89 to 890 m³/m³ (500 to 5000 scf/B). Any suitable dewaxing catalyst may be used.

In embodiments where the product of an aromatic saturation process will be a lubricant base oil, the input feed should also have suitable lubricant base oil properties. For example, an input feed intended for use as a Group I or Group II base oil can have a viscosity index (VI) of at least about 80, preferably at least about 90 or at least about 95. An input feed intended for use as a Group I+ base oil can have a VI of at least about 100, while an input feed intended for use as a Group II+ base oil can have a VI of at least 110. The viscosity of the input feed can be at least 2 cSt at 100° C., or at least 4 cSt at 100° C., or at least 6 cSt at 100° C.

A solution with 31.5 g of 30% NH₄OH and 39.6 g deionized water (DI) water was made. The pH of the solution was 12.55. To the solution, 20 g of 1,1,3,3,5,5-hexaethoxy-1,3,5-trisilacyclohexane ([(EtO)₂SiCH₂]₃) was added, producing a mixture having the molar composition:

1.0[(Eto)₂SiCH₂]₃:21OH:270H₂O

and stirred for 1 day at room temperature (20-25° C.). The solution was transferred to an autoclave and aged at 80° C-90° C. for 1 day to produce a gel. The gel was dried at 80° C. in a vacuum to remove most of the water and then fully dried at 120° C. overnight (16-24 hours). This produced an organosilica material support as a clear solid, which was converted to white powder after grinding. No surface directing agent or porogen were used in this preparation.

Aluminum Grafting

0.141 g Al(O-i-Pr)₃ was dissolved into 30 ml anhydrous toluene and 6 g of the organosilica material support was added to form a solution. The solution was stirred at 110° C. for 1 day (16-24 hours). The solid was collected by centrifuge and then washed with toluene and methanol. The collected solid dried in an oven under vacuum at 120° C. to form an Al-organosilica material support.

Binder

The Al-organosilica material support was mixed and extruded with an alumina binder and water. Extrusion can be performed on wet or partially dried material. Suitable catalyst can be in the form of a powder, granules, or a molded product, with particle sizes fitting between 400 and 2 mesh size (Tyler scale). The extrudates were calcined at ˜400° C. under an inert atmosphere (e.g. N₂) to prevent loss of surface area to obtain calcined extrudates.

Impregnation of Catalyst Metal

The calcined extrudates were impregnated with Pd and Pt salts by incipient wetness to create Catalyst 1. Metals salts can be added into the support+binder+water solution prior to extrusion. Metals can also be impregnated onto the support prior to mixing and extrusion. The impregnated material can be calcined under N₂ atmosphere to decompose the metals salts at temperatures resulting in good metals dispersion as defined by chemisorption. Calcination is not necessary if, for example, dispersion aids are used.

Nitrogen Adsorption/Desorption Analysis

Nitrogen adsorption/desorption analysis was performed on Catalyst 1 and the results are provided in Table 1.

Example 2 Aromatic Saturation Analysis

Aromatic saturation activity of Catalyst 1 tested on the petrochemical feed described below in Table 2 in a high-throughput experimental testing unit.

TABLE 2 Product Liquid after Baton Rouge DWO Feed Aromatics Property (H600N 65 ppm S) Conversion Total Aromatics (TA) by 2.57 L/g-cm 1.43 L/g-cm absorbance at 266 nm Sulfur by X ray 0.0073 mass % Nitrogen <5 ppm Density 0.86 g/ml American Petroleum 30.37 Institute (API) Gravity Aromaticity 3.6% Pour Point −7° C. Cloud Point 1° C.

For the testing, 0.08 g of Catalyst 1 sized to a 50/170 mesh was loaded into a batch reactor. After pressure testing with nitrogen, the catalyst was dried in nitrogen at 150° C. for 2 hours followed by reduction in 250 psig H₂ at 300° C. for 2 hours. The reactor was then cooled to room temperature and transferred to a glove box under a blanket of nitrogen. After opening the reactor under a blanket of nitrogen, approximately 3 cc of dewaxed oil was introduced to the batch reactor and the reactor was resealed. The aromatic saturation activity test was conducted for 12 hrs at 250° C. with 900 psig H₂.

The total aromatics were measured by UV-Vis adsorption test (using absorbance at 226 nm). The percentage of total aromatics converted was determined. The aromatic saturation experiment was run in triplicate to determine a standard deviation on the conversion and show statistical significance. Table 2 shows the results from batch testing for Catalyst 1. When normalized to the available metals surface area (SA), Catalyst 1 shows nearly equivalent aromatic saturation activity. The normalization was done using the estimated nanoparticle size from the 1/dispersion calculation.

UV-Vis experiments were done on a Perkin Elmer Lambda™ 850 spectrophotometer with Scantrag™ software by FTG. Samples were analyzed at room temperature (˜15-25° C.) in a ˜1 mm flow cell. If necessary, samples were combined with cyclohexane in solution to facilitate quantitative UV-Vis analysis.
